The Zero1 2GO Travel Data SIM is a 3-in-1 SIM card that supports Nano, Micro and Standard formats. 

The Zero1 2GO Travel Data SIM is a roaming data service. You need to switch on Data Roaming to use the service. There will be no roaming charges involved. After using the Zero1 2GO Travel Data SIM/eSIM, or if you switch to other SIM cards, please remember to turn off data roaming function to avoid unnecessary roaming charges.

The Zero1 2GO Travel Data SIM supports data service only. You can use data service for calls via Whatsapp, Viber and other such applications. 

The Zero1 2GO Travel Data SIM service supports Tethering on your mobile phone. However, do note that data consumption will be higher when you tether your phone to multiple devices. 

The amount of data available is dependent on the plan purchased. However, we do recommend that you use Wi-Fi for very data intensive applications. 

The Zero1 2GO Travel SIM service (whether using physical SIMs or eSIMs) consists of a data plan so you can connect to the internet during your trip and not have to worry about surprise roaming bills. This service does not include calls or text messages, but you can make calls and send text messages via WhatsApp or other similar apps as these work using data. 

The APN should be automatically set for you. However, if you still cannot access the internet, please turn off your phone and turn it on again (sometimes activating Airplane mode is sufficient). If you still have issues, please check the Troubleshooting Section for more assistance.
